How fast can polymer coated cast bullets be pushed?
People are using them in rifles...I think around 2500 fps give or take.
Thanks I've Been loading 10mm for close to 30 yrs. and have never approached max velocity, I would like to give it a go without having to shell out the money for jacketed bullets.
what kind of results have you guys been having with these bullets, both pushing them hard and moderate velocities???
I haven't started polymer coating my cast bullets yet. But I have driven some of my cast bullets from 800 fps to 1400 fps in 10mm and over 1800 fps from the 9x25Dillon.
For my 10mm I size at 0.4015" and use White Label's Carnauba Red that they use up to 2700+ fps. As I size with the STAR sizer, this lube fills the lube groove or grooves it is a fairly fast process.

I will eventually do some of the polymer coatings, but what I have been doing has been working well for me and is very cost effective...
I have poly coated a bunch of bullets for different calibers. 223 up to 45 ACP. I even coated some big 30's and loaded them in 300 win mag.
For plinking they do great. I have not done any serious accuracy testing yet.
